'UNITED STATES PETER SIVER'I'SEN, OF NEW YORK, N. Y.

SLICING IFACHINE.

Application filed April 18,

T all whom it may concern Be it known that 1, PETER SIVERTSEN, a subject of the King of Norway, and residing in the city of New York, county of 6 Bronx, and State of New York, have invented certain new and useful Improvements in Slicing Machines, of which the following is a specification;

My invention relates to slicing machines 1 and their appurtenances and has more particular reference to an arrangement for facilitating the machine slicing of objects at angles other than the conventional machine out, that is, at angles other than at right angles to the longitudinal axis of the object. More especially the present invention is adapted for the slicin of bologna and similarly dimensioned ob]ects. Bologna is/ customarily cut with a knife and generally at an angle of about forty five degrees to the longitudinal axis of the object, prima rily because most of the machines now in use do not afford the necessary convenience of operation to make it worth while using a machine to slice this type of object, and this applies even when a cut at right angles to the longitudinal'axisofthe object is to be made. A type of machine which is admirably suited to the slicing of this type of object, particularly when the angle of out is at rightan'gles to the longitudinal axis of the object, is thetype of machine disclosed in my prior copending application filed August 22, 1919, under. Serial Number 319,059'in which a specific example of a slicing machine is shown comprehending an inclined chute, '(V shaped in cross section) down which the object slides by its own weight. While this machine is suited to the cutting of slices at right angles to the longitudinal axis ofthe object, nevertheless by holding the object at anjangle'totheplane of the cutting mechanism on one of the faces of said chute, objects may be sliced at an angle to their longitudinal axis. While this manner of holding the object. effects the major purpose in a measure, it does not quite afford thenecessary support nor does it enable the slices to be as accurately uniformly and expeditiously cut as does mypresent invention, which provides an arrangement which affords adequate support for the object and at the same time ensures uniform angularity of cut. One example of 1922. Serial No. 555,034.

type of machine disclosed in my above men- M tioned copending application. Another example of my invention for accomplishing this result comprehends an arrangement for changing the angular relation of the feed- Way with respect to the plane of the knife, so as tochange the direction of feed with respect to the latter element. While I am aware that a construction is shown in the United States patent to Grraffnumbered 667,364 and dated February 5, 1901, which involves a chute rectangular in cross section, the vertical angular inclination of which may be changed with respect to the plane of the knife, the construction is infe'rior to my present invention primarily in the use of the inconvenient clamping elements. to feed the object, and the inconvenient movable knife.

Broadly stated therefore, one phase of my invention among others, comprehendsa cutting mechanism and gravity feeding means for feeding the object to be sliced to the cutting mechanism, the direction of feed relatively to the lane of the cutting mechanism being variab e. Whiletwo embodiments of the invention are disclosed, it is to be. understood that these embodiments merely serve as illustrations of the underlying principle of the in vention, and are not intended as "limiting the invention to. the specific forms disclosed in the drawings, these embodiments together with the description thereofbeing of such a ,nature as will enable those skilled in the art to practice the invention and to v. devise other equivalent modifications thereof ,without departing from the underlying principle of the invention. 1

In said drawings Fig. 1 is a side elevation of one embed,

imentrof the invention; I

Fig. 2 is a top plan view, of the invention shown 'inFig. 1;

Fig. 3 is asec-tion Fig. 4; is a side elevation of another modification of the invention, partly fragmen of Fig; 2 on the line hi}; 5 is a fragmentary end view of a modification of some of the elements shown in Fig. 4; I

Fig. 6 is an end elevation of the modificacutting mechanism co-operates with a tray B having a suitable mechanism controlled by the handle B for changing the elevation thereof with respectto the knife edge A" to' regulate the thickness of the slices. A reciprocating gravity feed holder, specifically taking the form of an inclined chute in the illustrated embodiment, is supported in asliding bracket C arranged, to reciprocate on the horizontal guide rods C". It

is to be'understoodthat a singlerod might be used instead of the double rods; if means were provided for preventing the sliding carriage from turning around the single rod. The foregoing elements are,substan tially similar to the corresponding elements shown and described in my co-pending application above referred to, and have no bearing on the present invention other than affording a specific application of the i1.- vention. My present invention, shown in Figs. 1, 2 and 3 has more special reference to the guide strip D, which is adapted to be attached to the inclined chute C. This guide strip preferably takes the form of an upstanding flange D and is of sufficient width to afford an adequate abutment for the object to be slicedin general about an inch and a half for the smaller sized bologna. While the present invention is more particularly designed for the purpose of slicing bologna and the like, nevertheless, it

is evident that the guide strip D might be used with larger objects when it is desired to slice ,the object at an angle other than thatafl'orded by the chute C, and this might entail widening the strip D as will be readily understood. In the embodiment shown in the drawings, this guide strip may be and preferably is formed with a slotted flange 1)" preferabl having its plane at right angles to the plane of the upstanding flange D to afford a secure footing for the device. Obviously, however, it may under certain circumstances be desirable to change the an ular inclination ofvthe upstanding flange with respect to the plane of the face of the chute to which this attachment is applied, in which event 'the angular relations ofthe planeofthe footing flange and the upstanding flange will be suitably altered. Y

In order to secure this attachment to the face of the chute C, one end of the member D may be and preferably is provided preferably drilled as above indicated, it is obvious that a rectangular shaped recess engaged by a bayonet shaped pin having a rectangular shank may under certain circumstances be found desirable when'it is desired to prevent the member D from rotating about the pin 10 as an axis. Obviously other methods of securing the end of the element D to the face of the tray may be used. Irrespective of the manner of attaching the end of the element to the face of the tray, it is desirable to provide additional elements for securing some other portion of the element D- to the tray, and this is particularly true when a drilled hole is used block having suitable locking means is preferably arranged to slide on one edge of the chute C. In the specific embodiment of -the invention illustrated, the slot in the flange D is indicated by 12, while the block is indicated by 13. The means for locking this block in position specifically takes the form of a set screw 14, adapted to bear against the rear face ofthe chute C. Instead of the set screw 14, obviously a spring friction element or the like might be located between one of thefaces of the block 13 and the face of the chute C to hold the block in frictional engagement therewith, thereby obviating the required, adjustment of the screw 14 in case it is employed. The arrangement is designed to normally provide a, cut of about 45 to the longitudinal axis of the object. Under some ClI'Clll'Ilstances, however, it may be found desirable to change the relative inclination of the element D with respect to the plane of the a pin 15 secured to the inner face of the block 13. Evidently the pin and slot arrangement just described affords means forkeeping, the block in such position'contiguous to the edge of the chute that the set screw 14 may be utilized in clamping the block to the chute C at all angles of member D within the designed limits. Obviously various equivalents of the pin and slot arrangement may be utilized. In view of the fact that some of the objects to be sliced for which the. present attachment is primarily designed are considerably longer than the chute C, it has been found, desirable although not essential to extend the upstanding flange D a considerable distance beyond the chute. In order to afford a sup- .to receive the pin 10. To this end a sliding To this end I the slot 12 of the flange D is engaged by port for the end of the object remote from the knife, a flange E is arranged preferably at right angles to the upstanding flange D and preferably lying in the same plane as the particular face of the chute C to which the entire attachment is secured, although the flange E might be concave. to better receive the bologna. It is quite evident that the flange E not only serves to support the end of the object projecting beyond the edge of the chute C, but also serves as a stop tolimit counter clockwise movement of the element D (whenviewed as in Fig. 2) when the flanges E and D are integrally formed as shown in'the drawings. It is evident, however, that the flange E might be arranged to slide in a suitable groove in the flange D and by connecting the end of this sliding flange to the block 13, the flange might be kept abutting against the edge of the chute C at all times.

The modification shown in Figs-4, 5, 6 and 7 disclose an arrangement which effects substantially the same result effected by the guide strip D in the above described modiiication. In this modification'the change in the inclination of the object with respect to the plane of the knife is effected by arranging the chute F so as to swing in two directions, thereby achieving its universal adjustability. In this modification, a rotary knife G similar to the rotary knife A, a tray H for regulating the thickness of theslices similar to the regulating tray B, and a chute F similar in configuration to the chute C, although not held in a per- .manent position with respect to bracket K as is the chute described in the previous modification, are provided. Chute F instead of being supported in bifurcated brackets as is the case in the construction shown in Fig. 1, is pivotally supported at.

- its lower opposite corners preferably by threaded trunnions J projecting from the chute F engaging bearings formed at the ends of the arms 16 and 17. The trunnions may 'carry clamping screws J to clamp the bearings formed onthe end of the arms 16 and 17 and the trunnions together, to prevent relative motion of the chute F and hold it' at a predetermined angle. The

arm 16 is preferably flared in the mannershown in Fig. 4 so as to provide a closure etwecn'thelower edge of the chute C and .the regulating tray K so that when the chute is elevated for example to the position shown by dotted lines in Fig. 6, sufficient abutment will be provided for the lower end of the object which is to be sliced to prevent its lateral, displacement. Preferably the arms. 16 and 17 are cast, or otherwise formed integrally with each other, arm 16 having a pin holder 18 recessed at 19, the recess being adapted to receive and hold a journal pin 20 the pro- The flange D jecting end of which enters bearings 21 formed in the bracket K. The longitudinal axis of this journal pin is arranged parallel to the lower edge of one of the faces of the chute F so that as the latter is swung around the journal pin 20, the lower edge of one of the faces of the trays F remains relatively stationary while the edge of the other face of the chute F rises from the plane of the knife. In order to lock the journal pin '19 to the bracket K, a set screw actuated by means of a handle 22 is arranged to lock the pin 19 to bearing 21. Instead of the clamping screws J shown in Figs. 4 and 6, for locking the chute F in predetermined position, it is quite evident that the arms 16 and 17 might be flared sharply near their junction to form an upstanding bracket M as shown in Fig. 5, thereby affording additional support to the chute F when in its normal position as indicated by .full lines in Fig. 6, and providing means through an elevating screw N for tilting the chute say to the position shown by dotted lines in Fig. 6. Since the elevating screw N will hold the chute F in predetermined position obviously the clamping screws J "may be dispensed with when this elevating screw is used.

The manner of utilizing the present invention and its mode .of operation is as follows:

The gravity feed chutes C and F are arranged to' reciprocate on the guide rods C. When it is desired to utilize the modification of the invention shown in Figs. 1 and 2, the guide strip D is moved to the desired angular position, which. may be readily ascertained from a suitable scale provided on the edge of the chute, and the object to be sliced is laid on the face of the chute adjacent to the guide strip D. The object may be guided by the finger of the operator, although obviously an arrangement for holding the object may be readily provided as for example a V's'haped chute similar to the chute C but on a small scale might be used to feed'theobject,'and. this small chute might be formed by using the flange D as one of the faces .of said chute, or an auxiliary pendent of the chute C-might be provided. having been moved to the desired position as above indicated, the set screw 14 is clamped tovhold the flange D in desired position. In'tlie modification shown in Figs. 4, 5

and 6, the chute F is swung about the trunchute entirely indecut-ting mechanism,

' sliced to said cutting mechanism,

knife G, which is driven by any suitablescription, it is not to be understood that these are the only modifications or equivalents, but are merel mentioned for the purpose of affording a clear understanding of the underlying principle of the invention.
